🔋 Self-Healing Armor Enables Electrode Integrity and Interfacial Stability for Durable Silicon Anodes

📝 پوشش خودترمیم کوپلیمر فلورینه بر پایه HFBA و MPS با ترمیم میکروترک‌ها و تثبیت SEI، پایداری چرخه‌ای آندهای سیلیکونی را در باتری لیتیوم-یون بهبود می‌بخشد.

💡 Novelty & Significance:
The novelty lies in an in situ UV-copolymerized self-healing fluorinated acrylate coating that repairs microcracks within one minute via reversible dipole-dipole interactions while acting as a fluorine reservoir to build a stable LiF-rich SEI. This dual mechanism enables durable silicon anodes, demonstrated in a 1.5 Ah pouch cell with 71.9% retention after 300 cycles and improved thermal safety.
